Quicksilver is alive and he'll look like the X-Men version. (I hope you don't mind the small update I made.)

Add DeadPool, Magneto, Mystique and a few members of the X-Men. (Examples: Cyclops, Jean Grey, X-23, Wolverine, Gambit and Storm.)

Ultron (MCU version because he's more better but has the body of one of his drones) discovers that the space stone is in Haven academy, steals it unnoticed and figures out that a part of the Reader is still connected to the space stone.

Ultron then meets Grogar, Sigma, Tammy and Phoenix-Person with the space stone instead of Death meeting Jedah and causes the problem in the first place.

Ultron proposes an alliance for peace while secretly hacking into Phoenix-Person.

Sigma notices that Ultron's hacking into Phoenix Person's systems but he doesn't interfere. In fact, he secretly shows him another way to take over the 4 universes.

Grogar sees that they're planning on betraying them and plans to find one of the infinity stones himself.

Sigma and Tammy create a special machine to connect themselves to each infinity stones power.

Tammy, Cozy Glow, Queen Chrysalis and Lord Tirek are the ones who got betrayed by Ultron, Sigma and PhoenixPerson, fought them and lost instead of Thanos.

Have Interaction with most of the characters with them being unsure of each other and on the first part of the arc and then when Twilight and Spike appears to tell the others what's going on back at her world.

After a 8 months of research with Tony Stark, Thanos, Dr light, Sci-Twi and Rick Sanchez, they realise that Ultron Phoenix Sigma is the reason why the universes are merged.

Iron Man, Sunset Shimmer, Leahcim, Zero and Chun-li disagree with Captain America, Thanos & MegaMan X's idea to get Cozy Glow, Queen Chrysalis, Tammy and Tirek out of their prison in XGard so they can get the rest of the infinity stones.

Thor's stops the fight and they agreed to go and get them.

Some of the characters from each franchise mentioned will be infected with the Sigma virus and won't be cured until the end of the arc.

——

For example:

Marvel: (the fantastic 4, Sentinels, She-Hulk, Rogue, Xgardians and Iron fist.)

CapCom: (Phoenix Wright, Vergil, Lilith, Trish, Asura and Akuma.)

MLP (the Mane-6 Except for Twilight and Spike, The pillars of old Equestria, Trixie and Starlight Glimmer.)

RWBY: (Team JNPR except for Nora, Team CFVY except for Velvet, Team SSSN except for Sun, Team STRQ except for Summer and Tai, The White Fang and Atlas Military.)

Rick and Morty: (Beth, Sqaunchy, Jerry, The galactic federation, The citadel of Ricks and Jessica.)

——

Rainbow Dash, Summer Smith, Ruby Rose and Thor get infected by the Sigma virus.

Black panther and princess Celestia have the time stone in ValKanterlot and everyone will be a pony.

Ryu, Hulk, Chun-li, Spike, Princess Twilight, and Captain America are handed the time stone from Black Panther and princess Celestia.

Grogar will find Jedah and talk about forming an alliance. He accepts and they find the Soul Stone in the dark kingdom, but they get corrupted by the stone without realising it and start kidnapped innocents to create a gigantic Symbiote.

The return of the Dazzlings and Maneiac Mayhem (under mind control) with Nemesis to protect M.O.D.O.K with the Mind Stone.

Commander Chris RedField, Frank West, Cyclops & Jean, SpiderGirl, Pinkie Pie and Fluttershy along with the Dazzlings take the Mind Stone from M.O.D.O.K but the Symbiote gets released.

The power stone will be in a core with a bomb in it containing the Sigma virus in KnowMoon-9 protected by Evil Morty, Juggernaut and the GrandMaster.

Yang, MegaMan X, Strider, Rocket Raccoon, Gamora and Zero get the power stone.

Each infinity stone will have a fragment of yourself.

Space: Your empathy towards others and self-apathy.

Reality: Your creativity and interests in life and multiverse.

Time: Your childlike spirit and your maturity.

Mind: Your intelligence and your silver tongue.

Soul: Your nobleness and kindness.

Power: Your physical strength and courage.

Wallflower Blush will babysit Adam, Roman and Tyrian while everyone is getting the rest of the infinity stones until they help stop Ultron Phoenix Sigma.

Cozy Glow, Queen Chrysalis, Tammy and Lord Tirek will realise they've been betrayed by Sigma, Ultron and Phoenix person.

Tammy equips herself and Queen Chrysalis with a device that will take away Ryu's Satsui no Hado and both of them be able to use the Satsui no Hado without side effects.
